WEST BOCA RATON, FL (WFLX) - Detectives still have questions about the West Boca mother that was in charge of the sleep over that turned deadly. Mysteries remain surrounding the apparent carbon monoxide poisonings of 11-year olds Caitlin Brondolo and Amber Wilson.

Now, according to authorities, the mother Loretta Wilson said she never left the car running overnight, has had problems with the car in the past, and at other times she had turned off the car and heard noises or fans still going off.

Palm Beach County Sheriff's Office originally claimed that before being transported, Wilson told investigators she had pulled her SUV into the garage, closed the door, but could not turn off the vehicle.

The mistake was made in the news release from PBSO.

Investigators are still investigating CO poisoning.

Caitlin and Amber, described as best friends and straight-A students, were spending the night at Amber's home in the Logger's Run development.

In the morning, 911 operators received some sort of aborted call from the house. Rescue crews arrived, finding the girls dead and high levels of carbon monoxide in the home.

Amber's mother, Loretta Wilson, suffered from exposure to the fumes as well but is expected to be okay.
